Abstract
A monostatic frequency modulator continuous wave radar for detecting and determining the distance to near range objects.
A temperature compensated one-port Z-network is provided to generate a voltage of equal magnitude and opposite sign to that of the voltage reflected from the antenna.
A temperature compensated one-port Z-network is provided to generate a voltage of equal magnitude and opposite sign to that of the voltage reflected from the antenna.
